		voltage or current	Page 4-8):
			Default: 0 to 20 mA (Ri = 250 Ω)
5	GND/AI2–	Analog input common
			0 to +10V (Ri = 200 kΩ)
			(10V to +10V Joy-stick control, selected with
			a jumper)
			Differential input if not connected to ground;
			Allows ±20V differential mode voltage to
			GND
6	24 Vout	24V auxiliary voltage	±15%; maximum current 250 mA all boards
	(bidirectional)		total; 150 mA from single board. Can also be
			used as external power backup for the
			control unit (and fieldbus).
7	GND	I/O ground	Ground for reference and controls
8	DIN1	Digital input 1	Ri = min. 5kΩ
			18 – 30V = “1”
