ICP DAS PET-2255 - 8 Channel Digital Input and 8 Channel Sink Type Digital Output
by ICP DAS

ICP DAS PET-2255

(P)ET-2255/(P)ET-2255-32 provides 8/16 wet/dry contact Digital Input channels and 8/16 sink-type Digital Output channels. With 2 Ethernet ports, (P)ET-2255/(P)ET-2255-32 allows daisy chain connection which permits the flexibility in locating devices, eases installation and lowers infrastructure costs. It features optical isolation for 3000 Vrms of transient overvoltage protection but doesn’t provide Channelto-channel isolation. Each input channel can be used as a 32-bit counter and each output channel can drive 650/600 mA load. The poweron value and safe value of digital output channel are programmable. It can safely be used in applications where hazardous voltages are present. It features 8 kV ESD protection, 4 kV EFT protection, 3 kV surge and 3000 VDC I/O isolation to enrich the noise protection ability for industrial environment.
