Description

Bulletin 700 Type RTC relays are designed for industrial environments. They
offer the reliability and accuracy of solid-state timing along with the contact
isolation of conventional electromechanical relays. The contacts are
hermetically sealed in glass for reliability.

Type RTC relays are available with up to two timed contacts and two
instantaneous contacts in any N.O. – N.C. combination. A sixteen position
rotary switch is used to set the mode to on-delay or off-delay, and there are
eight timing ranges in each mode. The timing period is set by means of a
self-contained potentiometer in the Type RTC relays. Relays with provisions
for an external timing adjustment potentiometer are identified as Type RTCR.

The N.O. and N.C. contacts are designed to be changed or added in the field.
A relay can be easily modified to have any combination of N.O. and N.C.
contacts, limited to two timed and two instantaneous contacts maximum.

Note

: If (2) Normally Closed (N.C.) contact cartridges are required for the

instantaneous positions of C5/C6 and C7/C8, they must NOT be field
installed. Please order this contact configuration direct from the factory.

UL Listed
