The module is plug & Play and support Hot – Swap
IM51B is an industrial high-speed 4G LTE Modem designed for use with the Brodersen RTU32 Series. IM51B is an LTE Cat 4 module optimized specially for
Utility and IoT applications. Adopting the 3GPP Rel. 11 LTE technology, it delivers 150Mbps downlink and 50Mbps uplink data rates. The IM51B support Worldwide LTE, UMTS/HSPA(+) and GSM/GPRS/EDGE that enables Brodersen RTUs to
communicate wireless telemetry data and SMS over public and private APN.
Connection management and maintenance is controlled by the RTU logic and provide an open wireless network connection for any network based communication
protocol like Modbus TCP, IEC60870 or DNP3. Main communication and power interface is USB 2.0 or backplane for RTU32M series. IM51B has built-in SIM card slot. External antenna is connected via the SMA antenna connector to provide good field strength to ensure reliable communication links. GPS is also SMA. In addition the IM51B has a watchdog interface for hard resetting the modem. Reset can be done from external or from Logic. IM51B is an LTE Cat 4 module optimized specially for Utility and IoT applications. Adopting the 3GPP Rel. 11 LTE technology, it delivers maximum data rates up to150Mbps downlink and 50Mbps uplink. IM51B compatible with UMTS/HSPA+ UC20/UC200T module and multi-mode LTE IM51B is backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 4G or 3G coverage. IM51B supports Qualcomm® IZat™ location technology Gen8C Lite (GPS, GLONASS, BeiDou/Compass,
Galileo and QZSS).

Introduction to LB2 I/O Series

The Brodersen LB2 I/O modules are designed for the RTU32M & RTU32N series. The I/O modules are in two parts, a bottom part containing the backplane bus, and a top part containing the I/O board and logic. All LB2 modules are hot swappable and equipped with a 200 MHz processor to process I/O, handle filtering, SOE, debounce, module clock and general module logic. Diagnostic variables are available for all LB2 I/O modules. Please see the module datasheets for full info.

Module firmware update is handled at the RTU level from the Brodersen WorkSuite.

Use only genuine Brodersen bus cables for connection to Brodersen RTUs and for extension of I/O module blocks. The connection cables for the LB2 backplane bus are designed to meet the power requirements and shielding to run high speed communications. The maximum overall length of a complete system is 30 meters. Each LB2 I/O module & power supply module is calculated as 2 cm. The cables are as the length indicates, e.g. UCC-610/1 count as 100 cm.

The maximum system configuration is 60 I/O modules on one LB2 Bus. If the configuration exceeds 60 I/O modules, an additional CPU is required. 

Benefits and features:
– Industrial terminal
– USB 2.0 Interface (also power interface)
– SIM card Nano front access
– Watchdog control interface
– DIN rail mounting
Order code IM51B
The IM51B modem is designed for working with the Brodersen RTU32 Series. Via modem drivers in the RTUs it establish connection over 4G/3G/GPRS.. to remote host/Servers. When a connection is established a new network connection is available for any network driver’s support by the actual RTU. The modem drivers control both connection details and maintain and monitor the connection. The connection management can be configured to be done automatically at power up or it can be controlled from the PLC logic. The IM51B has a DC input for enabling the watchdog. It is
provided to handle known problems with network provider system that occasionally can go into a dead lock – and the only way out is a complete hardware reset
(power cycle) of the modem. Using default RTU32 open Real Time Operating System it
offers access and support to a wide range of standard network protocols like TCP/UDP/PPP/FTP/HTTP/NTP/ PING/QMI/NITZ/SMTP/MQTT/CMUX/HTTPS/FTPS
