Page 4: Introduction
User Manual 1 Introduction The iSMA-B-W0202 has been built as an extension of Modbus serial bus by using wireless technology, wherever the use of network cable is impossible or unprofitable. Using two iSMA-B-W0202 modules allows to build a wireless 'bridge' for the RS485 by building wireless remote island (one or more) for devices, which communicate via Modbus RTU/ ASCII, e.g., iSMA-B-MIX18 or iSMA-B-MIX38. -

Monostable Relay In this mode, both rising and falling edge on the special input change the output state.
- Page 31 User Manual Time Relay NC [s] In this mode, if the output value is false, the falling edge on the special input sets the output to true. Every rising edge on the special input starts the counter from the beginning, which means that the output will stay true for a time defined in the Time Value register (expressed in seconds), counting from the last rising edge of the special input.
