Installation 2

2-2(Vol.2)

Power Wiring:

Power connections are made at the 2 position terminal block located on the module board

marked +5V and GND No. 8 captive wire clamps accept 10-16 AWG wire or spade lugs.

Power wiring conventions:

+ of the power source to the terminal marked +5V

- of the power source to the terminal marked GND

Power requirements

Voltage: 5.0- 5.4Vdc

Current: 250 mA + 25mA per digital module and 200mA per analog module.

Practices: In general it is good practice to reserve the +5Vdc power supply

exclusively for the task of powering one or more BASIC I/O ADs. As

with any microprocessor based equipment, reasonably clean power is

required for reliable operation. Sharing power with other devices such as

field signal transducers and contact excitation should be avoided
