* Specifications, color and design of the products are subject to change
without notice.
This product is a module to monitor isolation resistance of the
equipment in a live state that is driven by three-phase alternating current
power. Set this module to operate along with the CONPROSYS series
configurable type CPU module controller.
It has a function useful for early deterioration discovery in the equipment
powered by the three-phase and AC motors connected to the servo
amplifier or invertors, which are widely used in the FA factories or water
treatment facilities, for instance in a pump, and the system can be
examined while power is active.

Hardware Features
Find isolation deterioration in AC motor
This product finds isolation deterioration of the three-phase induction
motor by calculating isolation resistance from the measured applied
voltage as well as ground fault current to the three-phase induction
motor (low pressure three-phase motor) and AC servo motor.
With the Modes-IOTM measurement method, isolation resistance in a
live state can be accurately measured, and it is applicable to detect
isolation deterioration of the three-phase induction motor of AC motor.
The product can be set either in front of or behind the inverter and the
servo amplifier.
* The measurement method of TANASHIN DENKI CO.,LTD. is applied for
this product.
Compact Design
Compact design, 25.2(W)×94.7(D)×124.8 (H), features flexibility in
installation.
Adaptable to a temperature range between -20 and +60°C
The product is capable of operating in the temperature between -20 and
+ 60°C. It can be installed in the various environments.
Installation easy with two pieces of terminal support and DIN rail
You can install and remove a terminal connector without a screwdriver so
that it can shorten the time of the replacement.
As the product can be mounted and slid on a DIN rail, removing and
replacing are easy as well.
Equipped with LED for an operation check
The product has LED for an operation check, which helps you visually
confirm the communication status of each interface.
