Green:
• Steady In service.
• Flashing Internal failure, that is the internal signal INT--FAIL
is high.
• Dark No power supply.
Yel lo w:
• Steady Disturbance Report triggered.
• Flashing Terminal in test mode or configuration mode.
Red:
• Steady Trip command issued from a protection function.
• Flashing Blocked terminal, that is the internal signal INT--
TERMBLCK is high.
2.6 Input/output modules In the basic configuration of the terminal, one Binary input module and
one Binary output module are included. Up to 11 additional input/output
modules can be added. These additional input/ouput modules can be
placed freely in position S16 to S36 with these restrictions:
• Up to 5 Binary ouput modules and/or Binary in/out modules
• Up to 6 mA input modules.
Many signals are available for signalling purposes in the terminal, and all
are freely programmable. The voltage level of the input/output modules is
selectable at order RL48, 110, or 220 (48/60 V ±20%, 110/125 V ±20% or
220/250 V ±20%). The binary in/out module and the binary input module
are also available in an RL24 version (24/30 V +
20%).
2.6.1 Binary in/out module
(IOM)
The binary in/out module contains eight opto-isolated binary inputs and
twelve binary output contacts. Ten of the output relays have contacts with
a high-switching capacity (Trip and signal relays). The remaining two
relays are of reed type and for signalling purpose only. The relays are
grouped together as can be seen in the terminal diagram.
Note that the IOM can not be placed in slot 12, which is the first slot for I/
O modules next to the MPM module. This depends lack of space for a
contact on the rear of the IOM.
2.6.2 Binary input module
(BIM)
The Binary input module contains 16 opto-isolated binary inputs. The
binary inputs are freely programmable and can be used for the input logi-
cal signals to any of the functions. They can also be included in the distur-
bance recording and event-recording functions. This enables the extensive
