Question

What is a substitute product for ATS Pneumatic Timers?

Answer

1.It depends on ATS model. Refer to the following table.

Operating mode		ON-delay			OFF-delay
Operating method		Over-voltage time-limit operation			Non-voltage time-limit operation
Reset method		Self-reset			Electric reset
Contacts	Time-limit	SPST-NO/SPST-NC
	Instantaneous	---	SPST-NO	SPST-NO/ SPST-NC	---	SPST-NO	SPST-NO/ SPST-NC
Power supply		AC	DC	AC	AC	DC	AC
Model		ATS	ATS-10	ATS-11	ATS	ATS-10	ATS-11
		ON-delay operation			OFF-delay operation
		(1) H3CR-A8 + P2CF-8	(2) H3CR-A8E + P2CF-8		(3) H3CR-H8L + P2CF-8	(4) H3CR-H8L + P2CF-8 + External Relay

Note:

1.The ON-delay and OFF-delay operation of ATS could be specified by the orientation of the magnet section. Therefore there is no difference between the models with regards to the operating mode. When the moving part of the magnet section was at the bottom, it specified ON-delay operation, and when it was at the top, it specified OFF-delay operation.

2.he bottom row gives recommended substitute products or models with substitute functions. For details, refer to the following information.

2.There is no substitute product in column (1) because ATS utilizes the flow characteristics of air, which significantly differs in principle and construction with the current mainstream digital timers.
However, a substitute function can be created by using H3CR-A8 Solid-state Timer with P2CF-8 Surface Mounting Sockets.

3.There is no substitute product in column (2).
However, a substitute function can be created by using H3CR-A8E with instantaneous contacts with P2CF-8.

4.There is no substitute product in column (3).
However, a substitute function can be created by using H3CR-H8L OFF-delay Timers with P2CF-8.

5.There is no substitute product in column (4).
However, a substitute function can be created by using H3CR-H8L with P2CF-8, and creating an instantaneous contact with an external relay.

6.General Comparison of ATS and H3CR-A/H

Compared item	ATS	H3CR-A8(E), -H8L	Remarks
