Time control technique Pulse control timer BA 7864, EO 7864 MINITIMER® fia o • According to IEC/EN 61 812-1 • Time range up to 32 h • Seperate setting of impulse- and space time • For impulse- and space time 4 time ranges each • Repeat accuracy < ± 0.5 % • Setting on relative scale • Dual-voltage-version • Programmable for start with impulse or space • LED indication for opération and contact position • BA 7864 available with remote potentiometer contact Z1-Z2, Z3-Z4 • EO 7864 with 11-pole socket • Available with 1 or 2 changeover contacts, or semiconductor output (BA7864) • BA 7864: width 45 mm EO 7864: front size 35 x 48 mm Approvals and marking Application Time dependent controls indication red LED: green LED: on when operating voltage applied on when output relay activated notes By an external bridge via terminals 6-7 of the plug-in-socket the EO 7864 can be programmed for the start with space. The BA 7864.- - starts with impulse, whereas the special version of the device BA 7864.- -/010 starts with space. For the variants BA7864.81 and BA 7864.81/010 a remote setting of the impulse- or space time is possible via two external variable resistors. EO 7864 with front frame ET 4048-3 Function diagram 753
