Ethernet to 8 A/D, 2 Optically Isolated Dry Contact Inputs, 2 Solid-State Relay Outputs

Project description

The module provides eight single-ended or four differential A/D inputs that are software configurable for 0-5V, 0-10V, +/-5V, and +/-10V ranges. The A/D inputs support floating/non-referenced or ground referenced selections. This makes the A/D inputs ideal for measuring floating signal sources such as outputs of transformers, thermistors, and battery-powered devices. Additionally, the A/D inputs can operate in bipolar or unipolar modes.

The digital inputs are dry contact, switch-sensing inputs that are internally biased with 5VDC. When the contact closes, current flows through the circuit and an input condition is detected. The inputs are optically isolated and provide 1000VDC isolation to ground. The solid-state Form A SPST relays can switch up to 60VDC at 2.5A. Solid-state relays improve upon mechanical relays by having no moving parts, operating silently and having virtually unlimited switching cycles.
