OPTIONAL EQUIPMENT
LON-200
EH-485
Ouman has an EH-485 bus adapter card available as optional equipment
which makes the 203GL serial interface compatible with the RS-485 field
bus. This offers the choice of economically connecting the 203GT
regulators to the GSM-phone.
MODBUS-200 is a bus adapter card which makes the EH-203/GT serial
interface compatible with the MODBUS RTU field bus. The physical
interface to the field bus is galvanically isolated RS-485 network.
GSM-modem
When a GSM modem is connected to the regulator, a GSM telephone can
be used to communicate with the regulator via text messages.
EH-686
An input/output unit which contains relays, analog and digital inputs as well
as analog outputs. The unit makes it possible to carry out time controlled
relay functions, transfer alarms using digital inputs and make an individual
regulating circuit. EH-686 can also function as a master in the Ouman
RS-485 bus by directing traffic in the net.
LON -200 is an adapter card which changes the 203GT regulators' serial
communication bus so it is compatible with the LON field bus. An
installation guide comes with the LON-200 adapter card.
PAN-200
With the help of panel installation kit PAN-200 the regulator 203GT is
easy to install for example to the control cabin. The size of the installation
hole is 222 mm x 138 mm.
MODBUS-200
42
EH-net
203GT can be remotely used (browser-based) in the Ethernet network
using an EH-net server. The 203GT controller must have a Modbus-200
adapter card to enable an EH-net connection.
