Parameter		Value
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 VDC) and M (0 VDC); the M terminal is connected to the M terminal of the CPU via the I/O bus
