Air box convenience has valve terminal flexibility

Capable of replacing two ordinary AS-i air boxes, with significant savings, the CA44 AS-i valve terminals from Bosch-Rexroth can accommodate any two valves from the company's MC range.
Capable of replacing two ordinary AS-i air boxes, with significant savings in space and assembly time, the new CA44 AS-i valve terminals from Bosch-Rexroth can accommodate any two valves from the company's extensive MC range, including double-solenoid 4/2-way types. This provides exceptional flexibility, and allows up to four valve functions to be implemented in a single compact assembly. In addition, unlike conventional AS-i air boxes, the new valve terminals allow users replace valves easily, should their requirements change.

No alteration is needed to the AS-i addressing when new valves are fitted.

The valve terminals require only a single AS-i address, allowing the AS-i system to be used to its full capacity.

They are optionally available with four auxiliary digital inputs which use standard M8 plug-in connectors.

These inputs provide a convenient and cost-effective way of connecting position switches, sensors and similar devices to the AS-i network.

Designed for easy mounting on DIN rail, CA44 valve terminals use industry-standard AS-i coupling modules which incorporate an insulation-displacement connection system.

This means that new valve terminals are connected simply by clamping the coupling module in place at any point on the AS-i cable - no wire stripping is needed, and the possibility of incorrect connection or reversed polarity is completely eliminated.

The pneumatic connections are equally convenient.

They use standard PN connectors, all of which are located on the same side of the valve terminal, ensuring that the connections occupy the minimum of space.

Ideal for use in automation, handling, transfer and process engineering systems of all types, Bosch Rexroth CA44 valve terminals have an exceptionally long service life of at least 100 million operations, and can support flow rates up to 200 litre/min.

They are normally supplied ready fitted with the user's choice of valves, but are also available without valves.
