AT-13433 8 digital input and 8 digital relay output Modbus RTU module
  • AT-13433 8 digital input and 8 digital relay output Modbus RTU module

Product Description

AT-13433 – 8 Digital Input & 8 Digital Relay Output Module with Modbus RTU is designed for linking field signals or loads with compatible control equipment. It suits monitoring and automation work that needs the documented channel types rather than a general-purpose connection board. Interface support is listed as RS-485. Protocol support is listed as Modbus RTU. It accepts 9–36 VDC at the specified input. When choosing this industrial i/o module, start with the documented configuration. Match each signal or contact requirement to the field equipment. Channel count, communication, supply and isolation describe separate constraints; use the stated configuration information when planning the complete control system. AgSnO2, AgNi is specified for the contact material. The Digital Inputs specification is 8. The Input Type specification is Sinking. The Input Isolation specification is 5000 Vrms. The Logic Level 1 specification is Min. 6 V.
