Features

• Measurement Range: Alarm/ Normal.
• Measurement Rate: One reading each second.
• Communications Cable: RJ-45 to sensor using 15, 60, or 100 foot Helix High Temperature Cable, Maximum extension cable length 305m (1000 ft.) with approved low capacitance shielded cable or UTP.
• Sensor Disconnection Detection: Yes, using second contact.
• Sensor Power: Onboard dry contact relays, no power required.
• Trap Information: Alarm- Sensor Number, Sensor Description, Error/Normal.
• Input: Every switch has a pull-up resistor settable under snmp control. When used as an input the internal pull-up resistor can be turned on and a normal state configured. The input pin can then sense whether a switch is open or closed by the completion or interruption of the circuit.
• Output: Every pin can sink 20mA.
• Reboot: All settings are saved to EPROM memory. During the reboot period all I/O pins are tristate until they are set to their previous value under program control. All spurious signals are disabled during reboot.
• A/D Converters: Four 10-bit A/D converters. Each A/D is a successive approximation ADC. The ADC contains a sample and hold amplifier, which ensures that the input voltage to the ADC is held to a constant, level during conversion.
• A/D Converter Accuracy: ±2 LSB.
• A/D Conversion Time: 280uSec.
• A/D Integral Non-Linearity: 0.5 LSB.
