The SAR 4 and SAR 5 can be connected to a telecommunications connection line or a separate control voltage source (AC/DC) and is controlled by the ringing voltage or the control voltage. The SAR reacts either only to the ringing voltage or only to the control voltage and switches on an external signal generator (e.g. bell, horn or lamp) with its own or separate power supply. Operating voltage SAR4 230 V AC / 50 Hz Operating voltage SAR5 DC 24 V DC / 10 mA Operating voltage SAR5 AC 24 V AC / 10 mA Input / a/b TK connection line Input / ringing voltage 32 to 80 V AC Input / frequency range 23 to 54 Hz Input / impedance 10 kOhm at 75 V, 25 Hz Input / insertion loss less than 0.5 dB Input / insulation resistance greater than 5 MOhm at 100 V Input / a/c external voltage Input / control voltage DC 5 to 40 V Input / control voltage AC 5 to 40 V, 50 Hz Input / resistance approx. 6 kOhm Output / switching current max. 8 A Output / continuous current max. 6 A Output / switching voltage max. 250 V AC Output / switching capacity 1500 VA (AC) 240 W (less than 30 V DC) 50 W (greater than 30 V DC) Ring pause bridging 0 to 12 s Duty cycle limitation 0.25 to 12 s Electrical safety in accordance with EN 60950 Dimensions W x H x D 35 x 69.3 x 60 mm Operating temperature range -5 °C to + 55 °C Storage temperature range -20 °C to + 70 °C
