Description
16-channel Isolated DI Module
The I-7051 offers 16 channels for digital input, catering for both dry and wet contact, with an effective distance for dry contact of up to 500 meters. All channels not only feature Photocouple isolation, but can also be used as 16-bit counters. The I-7051D has 16 LED indicators for DI channel status monitoring. 4 kV ESD protection and 3750 Vrms intra-module isolation are standard. The hardware specifi cations for the M-7051 are the same as the I-7051 and both support the Modbus RTU and DCON protocols which can be confi gured via software.
