Built-in I/O

16 Relays

2A | 30VDC, 30VAC

Independently control: Low-voltage lights, motors, locks, solid-state relays (connected to larger loads), etc.

18 Digital Inputs

18 total | 16 Optically-Isolated | 1-16 3-26VDC, 17-18 0-5VDC

Monitor on/off state or configure as digital counters or frequency measurement. Monitor any contact closure.

4 Analog Inputs - 0-5VDC

0-5 VDC

Single-ended analog inputs to use with a variety of industrial or commercial sensors.

Up to 16 Temp/Humidity Sensors

1-Wire Bus

Monitor up to 16, 1-Wire temp sensors or 8 1-Wire humidity sensors (not included).

Peer-to-Peer Communication (P2P)

Control and Monitor up to 64 I/O

The X-432 can instantaneously communicate with other 400 Series devices through peer-to-peer communication. It can communicate with up to 32 other modules and allows you to control and monitor a total of 64 I/O points. If you use all the on-board I/O for the X-432, that's 10 additional endpoints. While the X-432 can control and monitor I/O on other 400 Series products as if it was directly connected to the module, it can also communicate with any ControlByWeb device.

Machine to machine (M2M) communication


Powerful I/O Controller Ideal for Simple PLC Functions

The X-432™ combines 3 major advantages: advanced programmability, 38 on-board I/O, and an easy-to-use digital interface. This powerful I/O device acts as a fully self-sufficient (or connected) IIoT logic controller for nearly any monitoring and control task - local or remote. 16 relays, 18 digital inputs, 4 analog inputs, and support for up to 16 temperature sensors make this a very capable device ideal for a great many applications in industries including Water/Wastewater, Energy and Building Automation.
