LC-131
3-channel Digital Input (16-bit counter) Module with Open/Short Detection and 1-channel Relay Output. RS-485 interface. Dry contact 10 ~ 30 VDC. Has operating temperatures of -25°C ~ +75°C (-13°F ~ +167°F)
Features
- Power Relay Output
- Dry Contact Digital Input
- Digital Input With Open/Short Circuit Detection
- +/-4 kV ESD Protection
- Tiny Form Factor with Easy Screw Mounting
The LC-131 is an easy-to-use digital input module, equipped with 3-channel digital input, functions open/short circuit detection, and 1-channel relay output. The digital input type is dry contact, meaning that wiring is easy. There are two methods of controlling the relay outputs, either directly from the digital input or via a remote host. Settings such as communication protocol and node address can be configured either via hardware or via software, depending on the setup. The module has also passed + / -4 kV ESD reliability test, and is designed to operate in extreme environments.
