If current mode (4-20mA) is used for an input without an external

resistor, connect a jumper from the terminal marked JMP to the terminal

marked RTN for that circuit.

If an input current device operates outside the 4-20mA range, connect a

resistor across the voltage inputs. For example, to measure 10mA to

50mA current loop signals, install a 100 ohm resistor.

If current mode is used for an output circuit, use the terminals marked I+

and I-. For outputs set up in current mode, the block’s internal power

supply can be used to drive loads up to 300 Ohms per output. For loads

up to 2K Ohms, use an external power supply. Connect the positive

lead of the external supply to one side of the load, and the negative lead

of the external supply to block common on terminal 29. If the external

supply is between 24V and 50V, you can use terminal 25 or 30 as a tie

point for the positive connection. This point will be disconnected from the

external supply by a reverse biased diode.

Removing an Electronics Assembly _______________

The block’s Electronics Assembly can be replaced with a compatible

model without removing field wiring or reconfiguring the block.

Pins

1. Unscrew the retaining screws at the top and bottom of the block.

2. Using a Block Puller (IC660BLM507), engage the tabs in the first

vent slots. Move the tool to the center of the block and squeeze the

handle.

3. Pull the Electronics Assembly upward.

Warning

If power is applied to the field terminals, power is also exposed on the

connector pins at the base of the Terminal Assembly, and electrical

shock hazard exists. Do not touch the connector pins! Death or injury

may result.

Inserting an Electronics Assembly

1. Align the Electronics Assembly in the guides and push down firmly.

Caution

Do not exert excessive force; it may damage the block.

2. If unusual resistance is met, remove the Electronics Assembly. If

power is applied to the block, DO NOT TOUCH THE CONNECTOR

PINS! Inspect the Terminal Assembly, connector receptacle, and

connector edge board (on the Electronics Assembly). Be sure the

keying matches. Remove any obstacles and reinsert the

Electronics Assembly. Pay close attention to the alignment of the

guide pins.

3. Secure the Electronics Assembly with the screws on the top and

bottom of the Terminal Assembly
