What is Hazard Monitoring Nwork?
HMN with “Leading Edge Intelligent Junction Board Technology”. HMN provides Intrinsically Safe Power/Communications to a wide variety of devices in Hazardous locations. The IFX Interface module bridges between the PLC, DCS or Computer and the Network. A 4-wire network interconnects Intelligent Junction Boards (IJB) and discrete sensors such as speed sensors (ISSs) and intelligent switch inputs (ISIs).
Applications for HMN technology include:
HAZARD MONITORING
MONITORING HIGH/LOW LEVEL SWITCHES
MONITORING LINEAR AND ANGULAR POSITIONS OF MECHANICAL EQUIPMENT SUCH AS GATES, INTAKE/EXHAUST LOUVRES, GRAVITY TABLES.
DISCRETE ANALOG INPUTS SUCH AS RTDs AND THERMOCOUPLES
DISCRETE DIGITAL OUTPUTS SUCH AS ISOLATED RELAYS MINI OPERATOR STATIONS FOR DATA INPUT AND DISPLAY
Carver Company offers a HMN System using "Digital Sensors" with a standalone or integrated PLC. An IFX Bridge allows for Ethernet IP, Modbus RTU or Modbus TCP.
Never has Hazard Monitoring been integrated to a simpler but yet dependable system. From the IFX modules an intrinsically safe 4-wire, shielded 18 ga communication/power line connects the IJB units. Each IJB has 4 or 6 galvanically isolated sensors inputs. The sensors can have leads of 1 to 50 feet long. The IJB units have a communication/power "IN" connection block and two "OUT" connection blocks. This configuration makes installation fast, easy and versatile. The total number of IJBs on a single network can be 40 units with 240 sensors and communication cable up to 5000 feet.
This FastScan System will integrate into your existing PLC or it will function away from your PLC on a standalone computer or other device.
The versatility of this system also allows the use of existing Type "T" thermocouples. The IJB-TC will convert the thermocouple sensors to digital at the IJB level eliminating the long and often times troublesome lead wire.
