- Product overview:
-
Digital signals from a programmable controller can be converted to
signals suitable for the connected devices such as a magnetic starter
(example: from 24VDC signal to 200VAC signal).
One terminal module supports connections with multiple devices with
different voltage loads.

- Merit.2
- Output modules (relay/triac/transistor) can be combined flexibly.
- Merit.3
- When a 64-point output module is used, output conversion for a maximum of 64 points can be made per one slot.
- Merit.4
- Sockets enable relay modules to be replaced individually. (Easy maintenance)
- Merit.5
- The spring clamp terminal block does not require screws.
Wires can be easily pushed into the conductive terminals without using
a screwdriver.

| *2 This indicates the assumption that the equipment is connected to a power distribution system, ranging from a public electrical power distribution network down to machinery within the premises. Category II applies to equipment for which electrical power is supplied from fixed facilities. The surge voltage withstand level for equipment with the rated voltage of up to 300V is 2500V. | ||
| *3 This index indicates the degree to which conductive material is generated in terms of the environment in which the equipment is used. In pollution degree 2, only nonconductive pollution occurs. A temporary conductivity caused by condensation must be expected occasionally. |
