RS485 Input Module
DAT3148-12
The device DAT3148/12 is able to acquire up to 12 digital inputs. The data are transmitted using the MODBUS RTU/MODBUS ASCII protocol on the RS-485 network.
The device guarantees high accuracy and stable measurement over time and temperature variations. To ensure plant safety, two Watch-Dog timer alarms are provided. The isolation between the parts of the circuit eliminates potential ground-loop effects, allowing the use of the device even in harsh environmental conditions.
The DAT3148/12 complies with the UL 61010-1 directive for the US market and the CSA C22.2 No 61010-1 directive for the Canadian market. The device is housed in a rugged, self-extinguishing plastic container, with a thin profile of only 17.5mm, allowing high-density mounting on an EN-50022 standard DIN rail.
The DAT3148/12 is designed to work with the MODBUS RTU/MODBUS ASCII protocol, a standard protocol in field-bus systems. This allows direct interfacing of DAT3000 series devices with most PLCs and SCADA applications available on the market. For protocol instructions, refer to the User Guide of the device.
