Functionality

4 analog inputs, individually configurable for	Not used (default setting)
	-2.5 V … +2.5 V
	-5 V … + 5 V
	0 … +5 V
	0 … +10 V
	0 … 20 mA
	4 … 20 mA

Resolution of the analog channels
- Voltage bipolar (-2.5 V … +2.5 V; -5 V … +5 V)	11 bits plus sign
- Voltage unipolar (0 V … 5 V; 0 V … 10 V)	12 bits
- Current (0 mA … 20 mA; 4 mA … 20 mA)	12 bits
LED displays	2 LEDs for process voltage and error messages
Internal supply	Via I/O-Bus
External supply	Via the terminals L+ (process voltage 24 V DC) and M (0 V DC); the M terminal is connected to the M terminal of the CPU via the I/O-Bus
