RS232 Deep Sea electronic PLC Basic Module , DSE555

We are authorized agent

Deep Sea Electronics PLC Basic module provides a number of control and monitoring features with

expansion capability to meet demanding specifiCAT-parts-partsions.

The ideal choice where a remote communiCAT-parts-partsions control system is specified (when used with one of the

comms output options below).‘Enhanced power measurement’ module provides all the functions of the

‘Basic’ unit but also includes full power monitoring instrumentation (detailed right) and powerful auto-sync

functions as standard.

The inclusion of auto-sync now allows the OEM to offer the choice of clean break or ‘Bumpless’ no break

transfers to and from the gen-set.

No need for complex sync panels etc.Simply use the 555 Power measurement module and interface to the

engine governor and AVR.(No break transfer using the 555 module requires connecting to a suitable

electronic governor and AVR.)Load control versions can be used to export a fixed amount of power to the

load while in parallel with the mains, with soft transfer to and from the gen-set.

Optional RS232 port allows comprehensive remote control and monitoring.

RS232 provides modem link to PC via PSTN line or GSM network (with suitable modem).Uniquely, the

module supplies DC power to the modem ensuring integrity of link during loss of mains and engine starting.

The module can also signal Engineers via the cell phone network using the GSM SMS messaging system to

advise of system alarms.

Optional RS485 ‘Modbus’ output. Using industry standard communiCAT-parts-partsion protocol allows full system

integration into new and existing building management and control schemes.

The 500 series modules have been designed for front panel mounting. The module is fitted into the cut-out

with the fixing clips removed.

These are then fitted from the rear. Connection is via locking plug and socket.
