Wiring

Terminal Arrangement

Precautions

Use ducts to separate input leads and power lines in order to protect

the Controller and its lines from external noise.

Solderless terminals are recommended when wiring the Controller.

Tighten the terminal screws using a torque no greater than 0.78 N·m,

or 8 kgf·cm max. Take care not to tighten the terminal screws too

tightly.

Power Blocks

The E5CK has independent power supplies for each of the terminal

blocks shown below. However, note that the power supplies for

blocks C (exclude relay output) and D are shared for the following

option unit.

• Option unit: E53-CKB or E53-CKF

Wiring

Power Supply

Input 100 to 240 VAC or AC/DC 24 V to terminal numbers 4 and 5 according to the specification.

Input

Connect the input to terminal numbers 6 to 8 as follows according to the input type.

Match the inputs with the internal jumper settings for each input type. For thermocouple or platinum resistance thermometer inputs, set the inputs

to a common position (TC/PT) as the temperature input.

Control Output

Terminal numbers 11 and 12 are for control output 1 (OUT1). The five output types and internal equalizing circuits are available according to the

Output Unit.
