R400 Series Modules

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.

Ethernet Module (M4223-USER)

Remote monitoring of indicator (for service technicians), Direct connection to the indicator from your PC application using standard sockets interface, to retrieve weight readings and configure settings, Remote PC serial port locate your PC away from the indicator and still access the indicator like it was connected directly to the PC on a serial port (M400-525)

  • Features

    • 10 TCP and 4 UDP bi-directional server sockets to interact with network port on the R400
    • 3 TCP and 4 UDP uni-directional sockets (listening) to interact with auto-output port on the R400
    • Simple configuration of network settings (DHCP, IP, Subnet mask, Gateway, DNS) from the R400 and web interface
    • Ability to access indicator as a serial port on a PC using M400-525
    • DHCP client built in for auto IP negotiation or static IP allocation
