AMS recorders are manufactured in several design versions, both modular and specialized. This allows for the appropriate selection of the device to the user's needs, both in terms of functionality and type of housing. AMS energy recorders count pulses from a maximum of 128 impulse energy meters equipped with impulse add-ons from "KWMS" type summary and billing devices. The recorders cooperate with energy meters of domestic and foreign producers. The sum of pulses from each line can be continuously or at set intervals (eg every 1 minute), re-transmitted on an ongoing basis to RTU telemechanics devices of the master system (eg SYNDIS). At the end of each measuring cycle, the counted pulses, separately for each line, are saved to a file in the non-volatile memory.
AMS Energy Recorders can be equipped with two to six serial transmission channels, enabling simultaneous, remote communication with the recorder and preview of accumulated values (per cycle, day, accounting period), cooperation with various telemechanics systems or printer operation.
Examples of AMS energy recorders solutions:
The AMS-3.1 recorder is designed to collect real-time data necessary to supervise energy management and to transfer this data to a supervisory system. It counts pulses from up to 32 impulse electricity meters with impulse adapters and from all summation and billing devices.
The recorder is made in the 6U modular technique with the use of SO-55v1x modules.
The basic version has the following modules:
The MSY-101 module identifies and counts pulses from connected devices and saves them in the non-volatile memory. The recorder works based on the LVDS bus.
The counted pulses can be continuously or periodically retransmitted to RTU telemechanics devices and to energy management systems such as SYNDIS Energia. The serial transmission channel implemented in this module enables remote communication with the recorder, preview of the calculated values and cooperation with other telemechanics devices. This is done via a galvanically separated RS-485 link or an optical fiber link. The MODBUS protocol is used as standard. Additionally, the DNP 3.0 or IEC 870-10x protocol can be implemented (to be agreed with the manufacturer). The device also has an RS-232 interface, which is used for configuration and testing. 
The SIM-400 pulse multiplier is designed for galvanically separated branching of pulses generated by the pulse inputs of energy meters and flow meters and leading them to the pulse inputs of two different summation and billing devices, eg AMS, DATAPAF. The adapter transfers pulses from one input to two independent outputs with the possibility of negation in channel 1 or 2.
The device requires an external power supply. It is made in a housing designed for mounting on a 35 mm DIN rail. 
The SPI-001 pulse multiplier is designed for galvanically separated branching of pulses generated by pulse inputs of energy meters and flow meters and leading them to pulse inputs of two different summation and billing devices, eg AMS, DATAPAF. The adapter transfers pulses from one input to two independent outputs with the possibility of negation in channel A or B.
As standard, the device is powered by 220V AC/DC. It is made in a housing designed for mounting on a 35 mm DIN rail.
