A2 IO moduli

A2 has multiple types of analog and digital input-output modules. All modules have the ISA connector. Their dimensions are 188 x 122 mm, which corresponds to 5HE standard. We offer all types of I / O modules, and some are in different variants so they can be used in many applications.

However, if a prospective customer has specific requirements so that existing modules can not meet these needs, Electronic Design can
offer development and production of specially designed modules by customer technical specification. The following standard I / O modules are available:

Analog input modules

Label	Number of channels	Resolution	Description
A2-28-AD	16 Se/Dif	12 bits	100 KHz, and 1K FIFO DMA. Isolating amplifiers with isolation between the channels and between the system and the external environment.
A2-28-IS	16 Dif.	12/16 bits	16 channels with channel isolation between the channels and between the system and the external environment. High performance and low price.
A2-28-MS	12 input modules	12/16 bits	A / D module, carrier up to 12 isolated, analog conditioners with voltage or current inputs for thermocouples, RTDs, potentiometers, measuring bridges, etc. The number and type of modules (conditioners) are configured by the user.

Analog output modules

Label	Number of channels	Resolution	Description
A2-21-DA	8	12 bits	Isolation between the channels and between the system and the external enviroment. Output current (4-20 mA) or voltage of ± 5 and ± 10 V.

Digital modules

Label	Number of channels	Type	Description
A2-87-DI	32	Digital input	Digital input module with optical isolation. Universal input levels from 3.3 V to 100V.
A2-87-RO	32	Relay output	32 Relays 1A, 24V. The module has an LED indicating when the channels are ON. Isolation at the level of the four relays.
A2-87-SO	32	FET output	32 FET output 24V, 0.5 A. The module has an LED indicator. Isolation at the level of the four channels.
A2-87-IO	16+16	Univerzal I/O	Module with 16 optically isolated inputs and 16 relay channels, 1A. Isolation was performed at the level of the four channels.

Counter-Timer

Label	Number of channels	Description
A2-07-CT	4, 8 or 12 counters and 1,2 or 3 frequency generators	Module for measurements in the time domain. 16/32 bit counters, frequency generators and quadrature decoders.

The modules are compatible with numerous software packages for data acquisition, measurement and process control - see: Software.
