905U-L-T Input Transmitter unit 905U-L-R Output Receiver unit
Radio: EN 300 220, Part 15.247, RSS-210, AS4295, AS4768.1 v compliant 89/336 EEC, AS3548, FCC Part 15, EN301489 Hazardous rating: Class 1 Div 2 (USA/Canada) Electrical: EN60950
Environmental Housing -40 to 60oC / -40 to 140oF, 0–99% RH (non-condensing) DIN-rail thermo-plastic enclosure. 100 x 22 x 120 mm / 3.9 x 0.9 x 4.7 inches.
SMA connector for antenna or coaxial cable connection. Power Supply 9 – 30 VDC. Power consumption @12VDC – Receiver 100mA. Transmitter 40mA quiescent, during radio transmission (30 msec) 300mA. Periodically scans AI to save power Analog loop supply internally generated, 24VDC 30mA Internal monitoring of supply voltage – may be transmitted as an "input" (Transmitter unit only) Hazardous rating: Class 1 Div 2 (USA/Canada) pending
Digital/Pulse Input, two inputs, suitable for voltage free contacts / NPN, or voltage input 0-1 VDC on / >3 VDC off Pulse input max rate 10 Hz, 50 msec on time, pulse input counted as 2 x 16 bit register.
Analog input, 0-20 mA, 4-20mA, span and zero configurable (default 4-20mA), "floating" differential input, resolution 16 bit, accuracy < 0.1 %
Thermocouple input, -20mV to +100mV, J, K or T type linearization with on-board cold-junction compensation, accuracy better than 1°C
Analog & thermocouple setpoint status, setpoint status sets (on) when input value < low setpoint and resets (off) when input value > high setpoint, status transmitted as per digital input, setpoint values are settable via frontpanel rotary switch or configuration software.
Digital Output, three relay contact outputs, 260VAC, 1A rating Analog Output, 0-20mA, 4-20mA, configurable span and zero (default 4-20mA), source output, 12-bit resolution, 0.1% accuracy. Comms-Fail, internal status based on configurable time-out value. Commsfail output. ok output, FET, 30VDC, 500mA Fail-safe, on "comms-fail", outputs user-configurable as retained (last correct value) or reset (fail-safe)
