Frequency / digital input indicator – totalizer
S311D is an indicator totalizer that accepts universal opto isolated digital input. Admitted signal types are reed, npn (2 wires or 24 V), pnp (24 V), NAMUR, photoelectric, Hall, 24 V input, TTL, variable reluctance. Digital input signal frequency measurement starts from 0.00015 Hz to 10 kHz. S311D supports increment or decrement totalizing of the digital input signal. Also it’s possible viewing the frequency measurement and/or totalized value. Programmable retransmission of the input value frequency is possible by the isolated analog output (voltage or active/passive current). Retransmission of the totalized value by the isolated digital output (Open Collector). Totalizer value is saved on non-volatile memory.
Loop powered isolator / universal converter (mA, V, Ohm, RTD, TC)
K121 supports input signals from Cu50, Cu100, Pt100, Pt500, Pt1000, Ni100, Ni120, Ni1000, TC J, K, R, S, T, B, E, N, L, potentiometer, voltage signals with ± 30 V and ± 150 mV scales and current (± 24 mA). The instrument also acquires potentiometer input with resistance between 500 Ω and 10 K Ω and resistances up to 1760 Ω. K121 features a reduced response time of only 140 ms for current and voltage input and less than 620 ms for other inputs. The accuracy class is 0.1% and the measurement conversion to 16 bit. K121 is ATEX certified II 3G Ex nA IIC T4 Gc X (gas) and II 3D Ex tc IIIC T135°C Dc X (dust).
Loop-powered temperature transmitter for RTD (Pt100, Ni100)
T120 is a high precision temperature transmitter for head mounting and is designed for universal use on machines, plants, installations and in the process industry to facilitate time, measurement costs, commissioning and maintenance.
The device converts the input signal from Pt100 (EN 60751) or Ni100 (DIN 43760) and retransmits it into a normalized current signal via a 4..20 mA loop-powered (2-wire technology) with 16-bit resolution. The transmitter is characterized by a high operating temperature range (-40…85°C), small size and fast connections via push-wire spring terminals.
All operating parameters are configurable via Windows software using a USB<->UART TTL converters such as EASY USB or S117P1 converter (USB<->RS232, RS485, UART TTL).
PT100 Thermoprobes
Temperature PT100 probes are devices supplying, through a physical process, temperature measurement to the instruments to which they are connected. These products can be used also in particularly heavy industrial application.
V / I converter with power for 2 wire transducers
K109S is a device that accepts mA/V signals able to convert it into mA/V standard signals. The device can power also all 2-wire sensors and all parameters are configurable through dip-switches. The power supply connection is available on the terminals or a special connector (K-BUS) allows a distribution of the power supply to the modules via bus connector. A 3-way galvanic isolation among Power supply // input // output circuits assures the integrity of your data.
Z-KEY | 2-port ModBUS industrial gateway / serial device server
Z-KEY is a device that extends networks and allows process data to pass between different IT and industrial communication architecture levels. Z-KEY guarantees the transmission of signals between Modbus TCP-IP/ Modbus RTU in 10 operating modes, increasing the number of nodes connected and the distances reached in the network. The device can also extend the serial network by operating as a Remote virtual COM transparent to the serial communication protocol.
The device is equipped with 1 Ethernet 100 Tx port and 2 serial ports (RS232/RS485, RS485)and it offers multiple configuration possibilities thanks to DIP-switches, web servers, and software tools such as SDD (Seneca Discovery Device), SESC (Seneca Ethernet to Serial Connection), EASY SETUP2. Advanced functions include advanced serial diagnostics, and “quarantine” mode with settable time for failing devices.
Z-PC | Data Acquisition Distributed Automation And Telecontrol Systems
Z-PC Line is a modular automation system for managing from a
single signal to thousands of I/Os. Z-PC series includes the maximum variety of I/O modules: digital inputs, fast counters, digital
relay and mosfet outputs, analog channels (mA, V, Ohm, mV),

up to 64 nodes without repeater and speeds up to 115 kbps. The
wiring of the power supply and the serial connection is facilitated
by means of a bus housed in the IEC EN 60715 DIN rail. Maximum data concentration is also guaranteed
Z-SG | Strain gauge input module with basic functions
Z-SG is a strain gauge signal converter. Measurements taken using the 6-wires or 4-wires technique are available through Modbus-RTU serial protocol or the analog output. Sensitivity from 1 to 64mV/V, settable by DIP-switch for integer values, via software for real/integer values by connecting to the device via the microUSB port on the front panel. Stable weight indication via Modbus register/digital output. Remote writing of the tare in volatile and/or non-volatile memory by digital input/Modbus register/Modbus commands.
