5 .1 Address Leaving these two pins (A, S) open, sets the address of the MTL831C/MTL831C- PS to “1” . A jumper on these two pins sets the address to “2” . Either is valid for a system with only one MTL831C/MTL831C-PS connected to the MTL838C. When two MTL831C/MTL831C-PSs are connected to a single MTL838C, they must be addressed uniquely. -
Page 9: Electrical Connections
Sensors connected to the MTL831C/MTL831C-PS should not be earthed. This avoids differences in earth potential that could affect measurement accuracy or damage the MTL831C/MTL831C-PS. If sensors must be earthed they should be POWER located close to each other to avoid differences in earth potential. -

Connect the data highway to a receiver for MTL831C/MTL831C-PS Transmitter #1 as in diagram below. Connect the MTL831C/MTL831C-PS Transmitter #1 data highway (+, S, and – terminal) to the equivalent terminals on a MTL831C/MTL831C- PS Transmitter #2. Install a jumper wire between the Address terminals (A and S) on MTL831C/MTL831C-PS Transmitter #2. - Page 12 MTL5553. The screen of a Data Highway cable between the MTL831C/MTL831C-PS transmitter and MTL5553 isolator is earthed to a local instrument earth in the MTL831C/MTL831C- PS’s field enclosure or the at the MTL5553’s enclosure.

Modbus. Note that the configuration data is actually held in the MTL838C for one or two MTL831C/MTL831C-PS Transmitters – depending on how many are connected. If an MTL831C/MTL831C-PS must be replaced for some reason, its configuration is automatically transmitted from the MTL838C to the MTL831C/MTL831C-PS when it is powered up. -
