The R400 Series flexibility is provided through its broad range of modules that are easy to configure and neatly connect into the rear of the indicator. There are 4 module slots where an indicator can be equipped with only the features required for a given installation.

Communication Modules
|
Communication modules are in addition the built in RS232/RS485 ports on the R400 indicators. These modules are all fully isolated and recommended for application where there is a risk of lightening or surges or where additional communication ports are required. M4201 RS232/RS232, M4202 RS232/RS485, M4203 RS485/RS485)

Input/Output Modules (M4301, M4311, M4321, M4331)
|
An R400 indicator can be equipped with up to 32 I/O. These I/O are electrically isolated, designed for direct connection into PLC's and are capable of driving low voltage actuators directly. Each module has 8 digital I/O ports which are limited to maximum input voltage of 30V and can drive up to 400mA.
|
Analogue Output Module (M4401)
|
The Analogue Module provides one isolated (>500V) 4-20mA or 0-10V analogue output. Update rates of up to 400Hz are possible with 1/65,000 resolution. Two digital I/O the same as the M4301 are also provided. It can be scaled to suit the input on the PLC. The fast update and high D to A conversion rate give a smooth output curve which helps a PLC to see more realistic readings (2.5msec step)
|
Button Module (M4302)
|
The Button Module provides 4 voltage free inputs for use with switches or thumbwheels. The voltage free inputs eliminate the need to wire up complicate input driver circuits.
|
Data Storage Device Module (M4501)
|
The Data Storage Module provides non volatile alibi memory storage (6M bytes) according to WELMEC 7.2 L. Compatible with later versions of software.
