Distributed I/O universal input module : Inputs : 1 analogue universal input : TC type: J,K,S,R,B,E,T,N; RTD (3 wires): Pt100, Pt1000, Ni100, Ni1000 ; mV, V, mA; Resistance (3 wires); Potentiometer; 3 digital input ; 1 analogue input (V or mA); 2 Relays SPST, 1 Open Collector Output. Baud Rate 38,4 Kbps. Max distance 1,2 Km. Power supply : 18...30Vdc. Galvanic Insulation: 1500Vac 50Hz., 1 min. MODBUS-RTU 485 communication protocol.
The DAT 3011 device is able to acquire RTD or Tc sensors, mV, V or mA input signals connected to the universal analogue input in engineering units in digital format. Moreover it is available a second isolated analogue input for V or mA. The device is able to acquire up to 3 digital inputs and to drive one solid-state relay and two SPST relays. The Data are transmitted with MODBUS RTU protocol on the RS-485 network.
The device guarantees high accuracy and a stable measure versus time and temperature. To ensure the plant safety two Watch-Dog timer alarms are provided.
The isolation between the parts of circuit removes eventual ground-loop effects, allowing the use of the device even in the heavy environmental conditions.
The DAT 3011 is in compliance with the Directive 2004/108/EC on the electromagnetic compatibility.
The DAT 3011 is in compliance with the Directive UL 61010-1 for US market and with the Directive CSA C22.2 No 61010-1 for the Canadian market.
The device is housed in a rough self-extinguishing plastic container which, thanks to its thin profile of 22.5mm only, allows a high density mounting on EN-50022 standard DIN rail.
