ELECTRO-SENTRY 1

 

Hazard Monitoring System for Single-Leg or Conveyor

Features

• Monitor 1 speed and 12 bearing and/or belt alignment sensors
• All sensor values and alarms are displayed on front panel
• Green, Yellow, Red LED's for each sensor to display alarms
• Direct interface to Electro-Sensors' speed and temperature sensors
• One-button tests for all sensors, set points, and alarm output relays
• Class II, Div 1 dust ignition-proof sensors for hazardous locations

The Electro-Sentry 1 is a hazard monitoring system commonly used on grain elevator legs or conveyors to monitor critical points for shaft slowdown, bearing temperature, and belt alignment as part of a predictive maintenance program to protect against catastrophic breakdowns and machinery failure resulting in product waste, machinery damage, and process downtime. All Electro-Sentry 1 sensors provide a standard 4-20 mA signal for reliability and accuracy.

ION REMOTE I/O

 

I/O Modules with Modbus

Features
  • 3 Models:
     - Analog-In
     - Discrete I/O
     - Frequency/Discrete-In
  • Standard Modbus RTU slave over RS485
     network interface, up to 115.2k baud
  • Low latency (< 1 mS) from Query end to Response start for high data throughput
  • Protected 24 VDC sensor power
  • Pluggable terminal blocks
  • DIN-rail mount
  • 24 VDC powered

High-quality sensor and control I/O at low cost.
All models directly connect to standard 2-wire RS485 networks of up to 31 Modbus slaves and a single Modbus master (PLC, PC, touch-screen, gateways, etc.).

Ideal for building scalable systems: expand by adding ION modules to the network.
Ideal for Hazard Monitoring systems: up to 12 temperature or shaft speed sensors per Analog-In module.

ION Analog-In

• 12 precision 4-20 mA analog inputs convert with 1µA resolution
• Ideal for Hazard Monitoring (temperature, belt alignment, shaft speed) systems

ION Discrete I/O

• 6 inputs - compatible with switches and NPN/sinking discrete-output sensors (e.g. prox, photo-eye, limit-switch)
• 6 relay outputs – Form-A (SPST) for controlling alarms, buzzers, motor starters, other relays, etc.

ION Frequency/Discrete-In

• 12 dual-purpose inputs – compatible with all pulse/square-wave frequency-output sensors and signals (shaft-speed, flow, pressure) and all discrete-binary sensors/switches (prox, photo-eye, switch, relay etc.)

• All inputs are separately configurable and independent:  acquire frequencies and discrete-binary states in any combination.
• High resolution (16 and 32-bit), high accuracy frequency measurement in any units (RPM, Hz and all user units)
• Separately configurable input termination (pull-up, pull-down and Hi-Z),  compatible with PNP/sourcing, NPN/sinking, line-driver and logic output sensors and signal sources.
