Onboard inputs and outputs
UIO Universal inputs and outputs support the following signal types:
● Passive sensors LG-Ni 1000, 2x LG-Ni1000, Pt 1000 (375, 385), NTC 10k (Type II / Beta (0-50 °C) =
3892 K), NTC 100k
● Resistance sensors 1000 Ohm, 2500 Ohm, 1000...1175 Ohm (for setpoint shift)
● Voltage input analog DC 0…10 V
● Current measurement analog DC 0...20 mA or 4...20 mA, (inputs U1, U2, U7, U8)
● Binary potential-free contacts for signaling functions
● Counter to 25 Hz (electronic switch to 100 Hz)
● Analog outputs DC 0…10 V
DO Relay outputs for binary controls, changeover contact
(NO, NC, pulse)
