Module overview
The TM800 alarm indicator and operator panels are based on a modular design. The appropriate
combination of modules will be made by Bender so that the user is not unnecessarily burdened with
planning details. This chapter provides a summary of the applicable modules:
BM800
Module for TM800 alarm indicator and operator panel
BM400
module like BM800, but without an LC display and control buttons
BI…
operating and display modules each with five illuminated pushbuttons
BMI…
I/O modules (digital inputs, relay outputs, open collector outputs)
Individual components (remote operating table control, intercom systems…)
3.4.2
BM800 and BM400 modules
3.4.2.1
BM800
Module for a TM800 alarm indicator and operator panel with LC display. BM800 features:
– LC display (without a front foil, because this is included already in the front plate of TM800)
– one operating LED, warning and alarm LED each as common alarm LEDs
– 5 control buttons
– Interfaces 2 x RS-485, 1 x USB, 2 x I²C
– Buzzer
3.4.2.2
BM400
BM400 is a module similar to BM800, but without LC display and control buttons. These operating
and display modules together with digital I/O modules can be configured to form indicator and op-
erator panels.
3.4.3
Operating and display modules
The operating and display modules consist of 5 elements. Depending on the panel type, different
numbers of modules are available (also see "Internal components and modules" on page 77ff).
Type Characteristics
BI800S
Operating and display elements to expand the BM800/BM400 modules. 16 BI800S
modules can be controlled via I²C bus. One individual function (switch, button, LED etc.)
can be assigned to each element.
BI71S
Operating and display elements without an I²C bus:
5 illuminated pushbuttons, 5 potential free changeover contacts, max. AC 250 V/8 A.
BI72S
Operating and display elements without an I²C bus:
5 illuminated pushbuttons, 5 potential free changeover contacts, max. AC 24 V/0.9 A
