OpenLine® analog modules communicate serially with the controller. Each module has a separate transmit and receive line that operates at 115,200 baud with no parity bits, 8 data bits and 1 stop bit 115.2k, N, 8, 1. The command structure and responses for all modules are detailed in Bulletin No. 743. Each module has a microcontroller and non-volatile serial EEPROM memory. The calibration data is stored within the EEPROM, and may be changed using the appropriate commands and the 70L-PROG field calibration unit. The software provided with the calibration unit communicates with the modules through the serial port of a PC. Calibration equipment is not provided.

**Digital Output Modules.** AC output modules have zero voltage turn-on of the load to greatly reduce generated EMI and RFI. They are highly immune to electrical transients, and have built-in RC snubber networks for increased capability with inductive loads. DC output modules can operate DC loads over a wide voltage range and have built-in voltage spike protection.

**Digital Input Modules.** The output of these modules is a logic level signal which corresponds to the status of the device being monitored. A high level output signal indicates the load is off the switch is open. A low level output signal indicates the load is on the switch is closed. Input modules are designed to give fast, clean switching by providing filtering and hysteresis.
