Applications

Automatic Meter Reading

Unit reports utility meter readings daily with up to 6 digits of meter resolution. During installation, unit is set to match the meter’s reading to allow for occasional verification of accuracy. It can be configured to store the reading at a particular time that may be different from the reporting time to ensure that meter readings from multiple meters are comparative. Model types include:

• AMR6-GSM: Same automated meter reading functionality as described above. Provides GSM digital cellular communications capability.
   
• AMR6-ORB: Same automated meter reading functionality as described above. Provides ORB COMM satellite communications capability.
   
• AMR6-SAT: Same automated meter reading functionality as described above. Provides Inmarsat D+ satellite communications capability.

Alarm Monitoring

Standard APM4AM models have a total of 6 inputs. Channels 1-4 can be configured as analog (±5 VDC, ±50 mVDC or 4-20 mA) or active digital. Channels 5 and 6 can be configured as digital, active digital, accumulator or accumulator reset depending on the model selected. Digital signal options are described below. Enclosure options include an anodized aluminum (can) and/or plastic box, depending on the model type. Model types include:

• APM4AM-GSM: APM4AM functionality with GSM digital cellular communications capability and can enclosure.
   
• APM4AM-ORB: APM4AM functionality with ORBCOMM satellite communications capability and plastic box enclosure.
   
• APM4AM-SAT: Data inputs operate like those of the APM4AMCP models but do not have surge protection or rectifier interface. Provides Inmarsat D+ satellite communications capability and plastic box enclosure.
   
• APM4AM-SAT WS: Features Wireless Sensor (WS) inputs - up to seven wireless transmitters can be used per unit, with normally closed contacts at each transmitter. Inmarsat D+ satellite communications capability.
   
• APM4AMCP: Designed for the corrosion professional, APM4AMCP models come standard with built-in surge protection and the ability to select from integral rectifier interface and/or test point filtering functionality. An optional AC Monitor, which converts AC voltage data into DC voltage data, is available. Channels 1, 3 and 4 can be analog (±5 VDC, ± 50mVDC or 4–20 mA) or active digital, and Channel 2 has the capability to accept input voltages up to ±100 VDC or active digital. Channel 5 can be configured as a digital, active digital or an accumulator, and Channel 6 can be a digital, active digital or accumulator reset. Enclosure options include plastic box.
   
• APM4AMCP-ORB: APM4AMCP functionality with ORBCOMM satellite communications capability and plastic box enclosure.
   
• APM4AMCP-SAT: APM4AMCP functionality with Inmarsat D+ satellite communications capability and plastic box enclosure.

Serial Data Terminal

Serial Data Terminal units interrogate modbus-compatible instruments via an RS232 connection and reports register readings based on a configurable, transmission interval. It reports up to sixteen 6-digit register readings, eight 12-digit register readings, or a combination of both from ASCII or RTU Modbus equipment. Model types include:

• SDT16-GSM: SDT functionality with GSM digital cellular communications. Can enclosure.
   
• SDT16-SAT: SDT16 functionality with Inmarsat D+ satellite communications capability. All compressor-related “shut down codes” are mapped to alarm descriptions. Plastic box enclosure.

Remote Interruption, Control, and On-Demand

Model types include:

• INT300: The INT300 is a satellite-based remote monitoring device that features over-the-air configuration minimizing hands on after deployment, and almost unlimited flexibility in I/O options, as well as RS232/485 used to communicate with a large variety of devices using the standard Modbus protocol.
   
• ICP+: Provides scheduled and by exception in-bound reporting and 2 way communication for on-demand reads and activating/deactivating ancillary equipment. Can be field upgraded to include a MicroMax® GPS80 current interrupter fpr IR-free cathodic protection (CP) reads. ORBCOMM satellite communications capability.
