Mounting bracket: OP-60412

Connecting the Unit to Sensor Amplifiers

When connecting DL-RB1A to the sensor amplifiers, the connection method varies according to the mounting type of the sensor amplifiers. Before connecting DL-RB1A, you must install any necessary expansion units to the main unit of the sensor amplifier. For information on installing the sensor amplifiers, refer to the user's manual supplied with the sensor amplifiers.

Caution

Make sure that the sensor amplifiers are turned off before connecting the BCD output unit DL-RB1A to them. Connecting the unit while the sensor amplifiers are turned on may damage the unit.
