∗1. Connection to certain motor controllers requires a Molex connector (referred to as "Molex connector"). Connection to the motor driver board requires a JST connector (referred to as "JST connector"). ∗1. The pump with a connector is required for use with the motor controller RE-C500/C501. ∗1. The pump without connectors can be used with RE-C100. ∗1. RE-C600 can be used with or without connector.

Stepper Motor Controller and Driver Board

This series is driven by a stepper motor.
To operate the stepper motor, a dedicated motor controller or driver board is required.
We offer the following motor controllers and driver board as a separately sold option. Please contact us if needed.
★ To use the driver board, you will need a pump equipped with wiring that includes
a JST connector compatible with the driver board (e.g., RP-TX***-***-DC24VS).

Motor controller RE-C600

Stepper motor controller for RP-HX, RP-TX, RP-QⅡB/C and RP-QⅢB/C series
Only one pump can be connected to the RE-C600.
Various pump operation sequences can be programmed using a PC connected to the RE-C600.
The pump can be stopped at a specified number of revolutions up to 30 revolutions, and a fixed discharge volume can be performed at a specified multiple of the discharge volume per revolution.
(Discharge volume data for one rotation is attached to the pump)
The program data of the operation sequence can be saved in RE-C600 and the pump can be operated without connecting to the PC.
Both with and without connector of motor wiring can be used.

Detail of RE-C600

Motor controller RE-C500/C501

Stepper motor controller for RP-HX, RP-TX, RP-QⅡB/C and RP-QⅢB/C series
A PC connected to the RE-C500 can control various pump operations.
Control 6 pumps with RE-C500
Up to 12 pumps can be controlled individually by adding one RE-C501.
Various pump operation sequences can be programmed.
The program data of the operation sequence can be saved in RE-C500 and the pump can be operated without connecting to the PC.
When connecting multiple pumps, different types of pumps can be mixed.

Detail of RE-C500/C501

Motor controller RE-C100 and Frequency counter RE-F100

RE-C100 is a stepper motor controller dedicated to the RP-HX / TX series.
Motor start / stop, forward / reverse rotation, and rotation speed adjustment are possible
Two pumps of the same type can be controlled by one RE-C100 (same operation).

The RE-F100 is a frequency counter that connects to the RE-C100 and displays the pulse frequency for setting the rotation speed.

Detail of RE-C100/F100

Stepper Motor Driver Board BD202411-T

A driver board used to connect the motor and power supply, and to control the motor via external control signals.
Please prepare your own control device to send the control signals.
A DC 24V, 1A power supply is required. Please use a DC power source, such as a DC power supply unit or AC adapter.
