I/O Module Installation and Wiring - I/O Terminal Block Wiring Diagrams

DC Output Module Wiring

The DC Output Module provides 16 current-sinking outputs in two groups of eight points per group. The two groups are isolated from each other; outputs are non-isolated within each group. Current sinking means that a positive voltage potential is continuously applied to one side of each DC output load, and the negative side of the load is switched internally in the module.

Specifications for this module and for other modules are given in the Specifications section of this manual. Examples of DC Output wiring are shown in Figure 43 - DC Output Module Wiring Diagram

Over-Current Protection

Electronic high-current and high-temperature limiting provides overload protection; resets after cycling power. Conventional external fuses may be used if desired.

Reverse-Polarity Protection

A potential of ± 34 Volts will cause no damage to the module; a reverse polarity power supply connection allows continuous current flow to the loads that are not controlled by the On/Off state of the output circuits.

Jumper Comb

Two-position jumper combs are available (as an option for barrier style terminal blocks only) for connecting digital common wiring between terminals 10 and 12, and for connecting +24Vdc between terminals 9 and 11. See Figure 44.

+V Terminals

The +V1 (terminal 9) and +V2 (terminal 11) are the positive power supply input to power the output circuits for the two groups of eight inputs per group. The +V supply must provide minimum 24 Vdc at 65 mA (min) per group.

Hazardous voltages exist at terminal blocks.

Using switches at field devices, disconnect the field wiring from power sources before servicing.

Failure to comply with these instructions could result in death or serious injury.
