•DigitalInputTypeSelection
General
The AMS400A Digital Input Type can be selected using two push-fit
jumpers on J and J4 on the main board.
• For volt free contacts use positions a-b and d-e.
• For Voltage Inputs use positions b-c and e-f.
The Digital Inputs are connected by these jumpers to the Analogue
input circuit. You can remove the jumpers to isolate the two circuits
for voltage type inputs. If you need higher isolation, remove linking
resistors R16 and R2 - marked with single black line (DC powered
units only).
