8-ch isolated digital input 3-CH digital output MODBUS RTU RS485 ZIGBEE

S7301 Zigbee input/output module has total 8 channels isolated wet contact or dry contact or open-collector input, 1 channel 0-24VDC analog input and total 3 channels isolated open-collector output. Output use RS485 or ZIGBEE wireless. Zigbee can realize the point-to-point, point-to-multipoint, multipoint-to-multipoint data transmission, can form a star, peer to peer and mesh network structure. Can build huge Zigbee wireless network through setting modules address, signal channel and net ID. The S7301 can work in terminal mode or router mode through configure parameters. Both of Rs485 and Zigbee use the industry standard Modbus/RTU protocol.

 Highlights:

l        Isolated digital inputs can be configured as 32-bit counter input

l        Input can be dry contact, wet contact, open-collector output

l        Static ,lightning protection for each input

l        The input channel number is configurable, can be set up from 1 channel through 8 channels, improve frequency for small count input

l        Analog input can use measure battery voltage

l        Isolated open-collector output can drive power relay directly

l        A lot of spare FLASH can be used to store user's parameters

l        RS485or ZIGBEE for optional

l        Zigbee wireless range can up to 3000 meters

l        Can detect RS485 or ZIGBEE automatically, no need jumper

l        You can tell us your requirement. We will update our firmware even after you received the modules, you can update your modules through RS485/ZIGBEE.
