The ET-7253 provides 16 dry contact digital input channels. Each input channel can be used as a 32-bit counter. It features optical isolation for 3750 Vrms of transient overvoltage protection but doesn’t provide channel-to-channel isolation. It can safely be used in applications where hazardous voltages are present. Modbus TCP Based Ethernet I/O Module with 2 Ethernet ports for daisy-chain networking, with 16-channel Digital Input, can be configured as Dry Contact Source type. Communicable over Modbus TCP and Modbus UDP protocol, Supports operating temperatures of -25°C ~ +75°C (-13°F ~ 167°F) and has a din rail mount.
