Two programmable differential current inputs (0 mA / 4 mA ... 20 mA, R
and one programmable differential voltage input
(-10 V / 0 V / 2 V ... +10 V, R
The analogue inputs are galvanically isolated as a group.

Six programmable digital inputs (common ground: 24 VDC, -15% to +20%) and a start
interlock input. Group isolated, can be divided in two isolated groups (see
and grounding diagram below).
Thermistor input: 5 mA, < 1.5 kohm
(high temperature), open circuit
Internal supply for digital inputs (+24 VDC): short-circuit proof. An external 24 VDC
supply can be used instead of the internal supply.
