RS485 card (code IROPZSER30)
Used to connect the DN33 via the RS485 serial network to the PlantVisor
supervisory system.

Analogue output module (code CONV0/10A0)
Converts the PWM signal for solid state relays (SSR) to a standard 0 to 10
Vdc or 4 to 20 mA signal. For models IR/DN33A7**** and IR33D7**** only.

ON/OFF module (code CONVONOFF0)
This module converts a PWM signal for solid state relays to an ON/OFF
relay output. Useful when the IR/DN33A7**** or IR33D7**** controller
needs to be used with one or more outputs to control solid state relays,
and at the same time one or more ON/OFF outputs are required for the
control functions or alarms.
